iterate

A command for sending a requested change to a Lovable project's coding agent and showing the resulting code difference.

In plain words
What is it for?
Use it to modify a Lovable project, inspect the unified diff, review edit history, or publish the result.
Why use it?
It adds approval steps for larger changes and makes the agent's edits reviewable before more work or deployment.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 14 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 185 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

iterate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Iterate on a Lovable project. Request: $ARGUMENTS

  1. Resolve the target project. If the user gave a name rather than an ID, call list_projects and confirm the project_id with them.
  2. For a non-trivial change, call send_message with plan_mode first so the user can approve the plan before code is written. This consumes build credits — confirm first.
  3. When the message completes (poll get_message if needed), call get_diff with the returned message_id and show the user the unified diff.
  4. Summarize what changed. Offer to iterate further, view history with list_edits, or publish with deploy_project.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

iterate is a command published in the GitHub repository lovablelabs/mcp (3 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 14 tokens to every session and 185 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
